I will plan on SLI 2 gtx 760, will this power supply handle it?
Case: NZXT Phantom 530
CPU: i5 3570k @4.2ghz 1.25V
GPU: GTX 760 EVGA ACX Cooler (not SC, reference speeds, better cooler)
Mobo: Asrock z77 Extreme4
HDD: Toshiba 500gb
RAM: 8gb 1600mhz Corsair vengeance pro
PSU; XFX pro 650w 80+ Bronze

The PSU has 1 12v rail that offers 52A, and has 4x6+2 PCIe connectors, although I see people recommending 750w psu, will the 650w psu be sufficient?

I have tested dual SLI 760s on my rig and I am amazed at how little power they use.

My 4770k is OC'd to 4.2 GHz and the 760s are both also OC'd.
I never see above 400 watts being drawn from the wall when gaming. That's from the wall!
I do have a platinum PSU, but still that power usage is nothing short of amazing for an overclocked SLI rig.

It will be sufficent. Thought 2 rails would be better imo for such a card but it will run it with no problems. I my self am running it on a Enermax 550 W.

Edit: Sorry missed the SLI part. 750 W would be a safer bet and you definently need 2 12 V rails
